Hey everyone, I hope all is well. I own a 1992 LS400 and I am having issues with my heater and temp guage. Here are the symptoms: -My car temperature guage will fluctuate between normal (slightly under half) and 3/4's high on the guage. When it goes up, it always comes back down to...

V8sprint...I attempted to send you a PM but the site is saying you are not able to receive Private Messages. I had to set mine up to allow this in my profile, so maybe you need to do the same? Anyhow, I would love to have you check on extra IACV's you may have. As for the procedure to check...

Update: I took the IACV out of my LS400, and gave it a once over clean. The unit actually looked in beautiful shape, and nothing appeared to be frozen or gunked up. But I cleaned it anyways and put it back in the car. Now my LS400, instead of idleing extremely low and stalling...is racing...

One other thing...I have had the car for over 4 years, and it does not seem to be handling as well as it used too...and the car cannot seem to hold a good alignment.

Thanks for the reply and the info. First off, the clunking/popping sound is coming from both front sides although it is worse on the passenger side than the driver side. It does not happen when braking, but only happens when you hit like a manhole on the road or a bump in the road. I...

Hey everyone. I own a 1992 Lexus LS400 with 135k miles on it. It is in beautiful shape but it has started to experience some issues with the suspension. I converted the original air suspension to normal struts about 2 years ago and about a year ago replaced the lower ball joints. However...
